• Question 32:

  The network of the future is the key to supporting the digitization and automation of many industries. This network should support diverse requirements from different applications using it. To do that, the network should have a new architecture. Which of the following best describe the elements of the new 5G end-toend network architecture?

  A. Wireless Access, Optical Transport, and a dedicated Core Network for wireless access running in a Central Cloud.

  B. Multiple access types (not only wireless), Optical Transport, Multi-cloud, and dedicated Core for every type of access.

  C. Public sector element, a smart city element, a health element, a transport and logistics element, and an industrial element.

  D. Massive Scale Access combining many wireless and wired access types, Smart Network Fabric as transport (combining optical and IP network elements, controlled by SDN), a Universal Adaptive Core network supporting all access types, a Multi-cloud system including central, regional, edge, public, private, and hybrid cloud, and Automation and Analytics providing flexibility in the network to serve different applications.

  Correct Answer: D

• Question 33:

  What is the main benefit of Cloud RAN?

  A. Increased cell coverage

• Question 34:

  You and a colleague are discussing the challenges to be resolved in order to make digitization and automation a reality in all industries. He is arguing that the solution is to have faster access connectivity, but you don't agree. You are trying to convince him of the need for an end-to-end solution. The new 5G network should be built end-to-end to enable industries' quest for value. What arguments can you provide to support your position?

  A. Increasing throughput is not enough. A faster and automated transport network, a distributed cloud where applications would run depending on their latency and reliability requirements, a core network that automatically handles any type of access, and a security framework to guarantee the security in every layer of the network are also needed.

  B. The network consists of many layers that include access, transport, core, cloud, and all of the applications running in the cloud. Increasing throughput in access is not enough. The bit rate needs to be increased in all of the other layers as well.

  C. Increasing the access throughput might be worthwhile but applications that support a higher bit rate should also be a consideration.

  D. Increasing the throughput is enough. There is no need to change the network end-to-end.

  Correct Answer: A

• Question 35:

  Which of the following is not a part of an E2E Network Slice?

  A. Cloud Slice

  B. Core Slice

  C. Access Slice

  D. Transport Slice

  Correct Answer: A

• Question 36:

  What is the maximum distance of an Edge Cloud from end-user?

  A. 1,000 KM

  B. 5,000 KM

  C. 10,000 KM

  D. 300 KM

  Correct Answer: A

• Question 37:

  Resource elasticity in Cloud enables which of the following actions? (Choose two.)

  A. Relocate VMs between data centers when a fault is detected.

  B. Deploy VMs across data centers when a new slice is needed.

  C. Add resources to existing VMs when traffic is high.

  D. Add VMs when traffic is high.

  Correct Answer: AD

• Question 38:

  Which of the following best defines what is meant by Network Slice isolation?

  A. Security + Cloud isolation

  B. Resource + Security isolation

  C. Transport + Cloud isolation

  D. Resource + Traffic isolation

• Question 39:

  What is the Unstructured Data Storage Function (UDSF)?

  A. This network function exposes 5G Core Network functionalities available to 3rd parties, so that 3rd party capabilities and events may be securely exposed by the Network Exposure Function (NEF).

  B. This network function is part of data repositories in the Common Data Layer. It stores 3GPP standardized data.

  C. This network function is part of data repositories in the Common Data Layer and in opposition to the UDR, it stores non-standardized ?Unstructured ?data.

  D. This network function stores or retrieves subscriptions, profiles, and authentication data to or from the data repositories. It offers services to the AMF, SMF, NEF and AUSF using the Service Based Interface.

  Correct Answer: A
